Abstract

PURPOSE:To obtain a titled device that can store thin plate strip by making one set or more of rolls of inner and outer roller cages or deflector rolls rotatable and reducing strip tension or thrusting force generated by winding force of the rotary storing device. CONSTITUTION:A strip S is wound by required number of winding on an outer roller cage (a), inverted by deflector roll 24, wound by required number of turns on an inner roller cage (b), bent inward by a deflector roll 36, changed in direction by a pull out guide roll 33, and pulled to outside. The cage (a) is rotated by driving of a driving gear 27 according to supply and pulling out of the strip S, and the strip S is discharged. In this case, a ring gear 17 is rotated by a driving gear 21, and a roller pinion gear 15 is rotated by the gear 17 through an idler gear 16 to rotate an inner roll 11. The rotation speed of the roll 11 is determined in accordance with peripheral speed of an inner spiral (d), that is synchronizing to rotation of the gear 27. As the spiral (d) is rotated by rotation of the roll 11, rotational resistance of the roll 11 generated by winding force is eliminated, and the tension of the strip S is adjusted to a required value.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slip storage device capable of converting continuous transfer, continuous transfer to intermittent transfer, and continuous transfer to temporary stop.

For example, in the production process of strips at a steel factory, continuous processing equipment for mass production is required, such as continuous pickling equipment, continuous cold rolling equipment, continuous annealing equipment, continuous plating equipment, etc. At the STRISOB feeding side of each facility, the strip coil is loaded into the unwinding device,
Performs intermittent work such as welding and connecting the preceding strip and subsequent strip, and on the IJ wrap output side, cuts the winding coil and strip, carries out the winding coil, attaches a frame to the tip of the slip, etc. In order to perform intermittent work,
11 Strip storage devices have been adopted on both the feed and feed sides.

As an example of a conventionally used strip storage device,
As shown in Fig. 1, fixed guide rolls a1+ a2 +

A trolley LC further equipped with a guide roll Rc is run 1.
The rollers are provided so that they can travel within a length l by a drive device T I), and the difference in speed between intermittent processing and continuous processing is absorbed by guide rolls Rb and Rd Jf'l. ing.

However, with these conventional devices, the scale of the devices has increased as equipment speeds have increased and mass production has increased, so small-scale storage devices have become obsolete due to the economical and inconvenient handling. In response to this demand, a rotary strip storage device was proposed.

Examples of the above-mentioned rotary storage device include those shown in FIGS. 6 and 4. In the device shown in FIG. 6, an outer spiral (c) is formed on the outer side of an outer roller cage (,) consisting of a number of rolls (17) arranged in a cylindrical shape, and an outer spiral (c) is formed on the outer side of the outer roller cage (,). 11!1 An inner spiral ((1) is formed on the outside of the inner roller cane (b), which is formed by cylindrically arranging a number of roller canes) concentrically inside the roller cage 7(α). , the strip (8) passes between the rolls (g) of the outer roller cage (α) and is connected to the inner spiral ((1)) and the outer roller cage (a).
) rotates, the outer vortex (c) rotates and the number of turns increases, and the inner vortex fd) increases the number of turns, and slip I/slip (s) is stored.

In this case the strip (s) is attached to the outer roller cage (α
) is pulled from the rotation.

When releasing the strip(s), remove the strip from inside 1.
Pull it out from the inside of the roller cage (d). As the strip is drawn out, the outer roller cane (σ,) rotates in the opposite direction to that described above, reducing the number of turns of the stored outer spiral and inner spiral.

In the one shown in FIG. 4, the slip (s) is forced into the outer roller cage (α) from the outside and forms two spirals between the outer roller cane (α) and the inner roller cage (b). (c) and (d) are formed and stored, and are pulled out from the outside of the inner roller cooler/(b) to the inside and sent out to the outside via the direction changing inclined roller (f).

These two spirals (c) and (d) are connected via a free reversal loop (g) formed by free elastic bending action, and are wound in opposite directions. The operation of storing the strip (S1) in the outer spiral (C) and the inner spiral (dl) is achieved by pushing the strip (S) in and supplying it, and increasing the number of turns while rotating the outer spiral (C). is rotated in the same direction, and the slip (S) is wound around the outside of the inner spiral (d), increasing the number of turns.On the contrary, when releasing the strip (Sl), the slip (S) is wound around the outside of the inner spiral (d). Pull out the slip (8).Strip (s)
, the inner spiral (d) rotates while decreasing the number of turns, and the free reversal loop (c) rotates in the opposite direction to the above, and the number of turns of the outer spiral (c) also decreases.

Although there are differences in the method of storing the strip in the two examples, in both methods, the winding force is generated as the number of turns increases, and the number of turns of the inner and outer spirals required for storage and release is increased.
This requires a force related to seaming force.

The force required to generate the seaming force and rotate the inner and outer spirals has various properties as described below.

First, the example shown in Figure 1 (one-bow included type) will be explained.

FIG. 5 is an explanatory diagram of measuring the tension of the strip (Q) with the strip (S) stored, and the tension at the measurement point is 1. ...1° shown as 1.8 In the figure, (i) and (j) are Tiflec rolls, and (k) and (1) are spiral guide rolls.

Upper Me F. ... ・When the strip (s) at 8 points of F is determined with 1 long sword, the tension T becomes 1 in Figure 6 toward the downstream side.
・) 1 and Do 2 and 1 ("3. The tension T increases between J-p4, but this is due to the outer roller cooler 7 (cL) as is clear from the comparison with Fig. 5. This is due to the seaming force.In other words, the tension imparted by the seaming force is due to the rotational resistance of the roll based on the seaming force, but it is also due to plate bending or rotational resistance of other rolls, etc. It's noticeably thicker.

If the strip tension increases as described above, the force required to draw in and pull out the strip must be large, and there is a risk that the slip may break.

Next, the adverse effects of increased seaming force are the same for the example shown in Figure 4 (push type), and the outer roller cage (α
) The winding force increases on the outer spiral.The force that rotates the outer spiral becomes thicker, and the strip that cannot resist the rotational force and is pushed in buckles and becomes unable to store, and the tension on the drawer side also increases. It is necessary to increase the power required to pull it out, and the sl-IJ tube may break as described above.

The present invention has been developed in view of the above circumstances, and it reduces the strip tension or pushing force caused by the seaming force in a rotary storage device, and also makes it possible to store the lip in a thin plate strip. This is a book that makes it possible to realize a type storage device, and its gist is that all or at least one set of the rolls of the inner and outer roller cages or the Delph rolls can be driven to rotate.

The outer cylinder (5) has outer rolls (a) arranged and pivoted so as to have a substantially cylindrical shape concentric with the substantially cylindrical shape formed by the inner roll αυ to form an outer roller cage (a). A window hole through which the strip (8) can be passed is bored at the required position of (5), and a deflector roll (C) is installed in place of the outer roll (A) at a position opposite to the window (C). establish.
